Biophysical Environment
The area near the surface of the earth can be divided up into four inter-connected "geo-spheres:" the lithosphere, hydrosphere, biosphere, and atmosphere.
Atmosphere
The atmosphere is the body of air which surrounds Earth. It is held near the surface of the planet by Earth's gravitational attraction. Lady Robinson Beach is best known for it's serene weather and atmosphere. The temperature at the beach averages 14 degrees Celsius during Winter, with wind speeds that predominately reach up to 16.1km/h.
Lithosphere
The lithosphere is the outer part of the Earth, consisting of the crust and the upper mantle. Originally the entire length of Lady Robinson Beach was backed by a series of sand dunes. These were a result of coastal processes and provided protection for the beach from storm surges. The dunes have a distinct structure, including three vegetation zones that all aid in the protection of the land from coastal processes. As shown in the diagram below, the formation of the beach has changed due to the waves coming in and washing the sand away which gives the beach its shape.
Hydrosphere
The hydrosphere is composed of all of the water on or near the earth. Lady Robinson Beach lies on the western shore of Botany Bay. Since the bay has a narrow opening into the Tasman Sea (approximately 1.1 km wide) it's a relatively sheltered body of water. This means that the water at Lady Robinson Beach is calm and usually receives low swells and wind waves.
Biosphere
The biosphere refers to an environment within the Earth in which living organisms exist. Lady Robinson Beach provides a habitat to support multiple types of different organisms. The most common are fish and sea grass. The fish at the beach attract many fishermen who enjoy fishing along the groynes. The seagrass, most popular along the shore of Lady Robinson Beach, also plays a vital role in providing food and shelter to a variety of organisms.
